How much CO2 are YOU producing?

How much CO2 was there before?

Measurements of CO2 levels in Ice cores collected in Antarctica and Greenland indicate that the preindustrial carbon dioxide level was 278 ppm. Between 1000 and 1800 A.D. that level varied by no more than 7 ppm.

What about human activities?

The CO2 levels have now reached 386 ppm, which means human activities have increased the concentration of atmospheric CO2 by 109 ppm or 39 percent.

[Note: On various websites reporting the carbon dioxide emissions since 1750 the cumulative amount varies from about 1.3 – 1.8 trillion tons. On one website the amount is published once as 1.36 trillion tons and again as 1.71 trillion tons of CO2 on separate pages. Understandably, no sources are quoted. ]
